Excellent facility. Took my toddler there for a children's play session. Loads of equipment for them to play on, am not an expert so can't name them properly but he particularly enjoyed the foam pit and the obstacle course.
A very friendly & welcoming club, with fabulous facilities and knowledgeable coaches. They have classes to cover all ages & abilities, from pre-schoolers to adults.
Took my niece here. She loves going. Should be more viewing options for people who are staying to watch there children though. It's a tiny room at the top.
Seemed to have good enough facilities but we were just visiting so don't know too much about the club. If you're in N Walsham you won't have a choice for proper gymnastics anyway, without travelling.
